复制代码 代码如下:
function cal_pace(d,h,m,s){
 var distance = d;
 var hours = h;
 var minutes = m;
 var seconds = s;
 if(distance.length > 0 && hours.length > 0 && minutes.length > 0 && seconds.length > 0)
 {
  var speed = parsefloat(hours) * 60.0 + parsefloat(minutes) + parsefloat(seconds) / 60.0;
  speed = speed / parsefloat(distance);
  var speed_minutes = math.floor(speed);
  var speed_seconds = math.floor((speed - speed_minutes) * 60.0);
  return (speed_minutes + '\'' + speed_seconds + '\').tostring();
 }
 return '0\'0\';
}
